Put a twist in your next jewelry idea with this 30mm silver-plated interchangeable bail. Its large, bell shape is finished with a brilliant silver color and features small detailed swirl shapes along its edge. The top of this bail slides back and forth so you can open it and always change what it will hold. This component is designed to hold 30mm sized Swarovski 4439 and Swarovski 4437 square rings, so explore different color combinations to use in your jewelry. This bail will work best if you slide the front of the bail through the back of the crystal.
